# Charles River Laboratories: Business Model & Revenue Engine



## Direct Answer

Charles River Laboratories reports revenue across 3 business segments in its fiscal 2025 Form 10-K. Discovery and Safety Assessment is the largest, with $2.4 billion of revenue (60% of the total), followed by Research Models and Services at $846 million (21%). 53% of revenue came from the United States.

## How Does Charles River Laboratories Make Money?

No single line supplies a majority of revenue: the largest, Discovery and Safety Assessment, is 60%, which spreads Charles River Laboratories's exposure across several demand drivers. Between fiscal 2024 and 2025, Research Models and Services grew fastest (+2.0%) and Discovery and Safety Assessment slowest (-2.0%), so the revenue mix tilts toward Research Models and Services while that gap lasts.

| Segment | FY2025 revenue | FY2024 revenue | Share of revenue | Change |
| --- | --- | --- | --- | --- |
| Discovery and Safety Assessment | $2.4 billion | $2.5 billion | 59.8% | -2.0% |
| Research Models and Services | $846 million | $829 million | 21.1% | 2.0% |
| Manufacturing Support | $766 million | $769 million | 19.1% | -0.4% |

## Which Charles River Laboratories Segments Earn the Most?

| Segment | FY2025 segment operating income | Segment margin |
| --- | --- | --- |
| Discovery and Safety Assessment | $425 million | 17.7% |
| Research Models and Services | $45 million | 5.3% |
| Manufacturing Support | -$184 million | -24.0% |

Segment operating income is the profit measure Charles River Laboratories reports to its chief operating decision maker for each segment. It usually leaves out corporate costs that are not allocated to a segment, so the segments usually add up to more than consolidated operating income, and margins are comparable within Charles River Laboratories more safely than against another company.

## What Does Charles River Laboratories Sell?

Charles River Laboratories also breaks revenue down by product and service line, which shows what customers pay for rather than how management organizes the business.

| Product or service | FY2025 revenue | FY2024 revenue | Share of revenue | Change |
| --- | --- | --- | --- | --- |
| Service | $3.3 billion | $3.3 billion | 80.9% | -1.6% |
| Product | $765 million | $746 million | 19.1% | 2.6% |

## Where Does Charles River Laboratories's Revenue Come From?

Regions follow the definitions in the filing; most companies assign revenue by customer location.

| Region | FY2025 revenue | FY2024 revenue | Share of revenue | Change |
| --- | --- | --- | --- | --- |
| United States | $2.1 billion | $2.2 billion | 53.3% | -4.4% |

## What the Segment Figures Do Not Show

The rows above add up to 100% of Charles River Laboratories's reported revenue for fiscal 2025; the difference is intersegment eliminations, corporate revenue or items the company reports outside its segments. Segment definitions are management's choice and change when a company reorganizes, in which case it restates prior years in the next filing, so a multi-year comparison should use the figures from a single filing. Revenue shows where sales come from, not where profit or cash is earned: a small segment can carry most of the margin.

## Where These Numbers Come From

Every figure on this page is a value Charles River Laboratories reported in the segment note and revenue disclosures of its Form 10-K filed February 18, 2026 (accession 0001100682-26-000022), read from the SEC's Financial Statement Data Sets. The prior-year column is the comparative figure from that same filing, so it reflects any restatement for a change in segments. Category names are the company's own XBRL labels, lightly reformatted for reading.

Rows that only total other rows (for example a "Products" line beside the individual products) are left out so nothing is counted twice. This page is educational and describes reported history for fiscal 2025; it is not a forecast or a recommendation.
